CONCRETE RAILWAY-RAIL SUPPORT.

Patented Mar. 1, 1910.

Application filed April 12, 1909. Serial No. 489,338.

To all whom it may concern Be it known that I, WILLIAM LAUDAHN, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented certain new and useful. Improvements in Concrete Railway-Rail Supports; and I do, declare description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

This invention relates to improvements in concrete railway rail supports.

The object of the invention is to provide an iniproved construction of cement supports for railway"i'ails whereby the latter will'be securely anchored or held in position and revented from spreading.

A furt ier object is to provide a support of this character by means of which the, use of spikes or similar fastening devices is dispensed with.

With the foregoing and other objects in features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings, Figure-1 is a plan view of a portion of a railway showing the application of the invention thereto; Fig. 2 is a cross sectional view on the-"line 2-2 of Fig. 1; Fig. 3 is a similar one of the intermediate rail supports taken on'the line 4 4 of Fig. 1; andshowing the construction of the cushioning plates arof one of the supporting blocks; Fig. 6' is a- SlIlllltIlfVlGW of one of the combined cushi iomng and t e-bar -attach1ng plates of the su ortin blocks: Fi 7 is a similar view I i of? one of the wear and cushioning plates of the-intermediate supporting blocks; Fig. 8

' is a side View of one of the main supporting to; which the tiebars are connected and blocks showing the angular engaging plates l tionof said plate; Fig; 9 is a perspective l view of one of the block engaging plates; j Fig. 10 is a perspective view of a modified l form of supporting block; Fig. 11 is anl "end elevation of the same showing the rail secured thereto; Fig. 12 a detail cross I sectional view similar to F 1g. 2

showing a l thereof and view, the inventlon consists of certain novel l different manner of connecting the rail tie rods with the rail.

Referring more particularly to the first nine figures of the drawings, 1 denotes the main supporting blocks and 2 denotes the intermediate supporting blocks of the rails, said blocks being formed of cement or other form of concrete material. The blocks 1 and 2 are each provided in their upper sides with longitudinally disposed rail receiving channels 3. In the channels 3 of the main supporting blocks 1 are arranged tie bar connecting plates 4, said plates comprising a bottom portion having along its opposite edges upwardly turned flanges 5 which, when the plates are in position lie between the edge of the base flanges of the rails and the adjacent inner walls of the channels 3 thereby preventing wear on the base flanges of the rails and walls ofthe blocks. The opposite ends of the bottom portion of the plates are ente nded beyond the flanged edges said extended ends project beyond opposite sides of the plate to form attaching members 6 which, when the plates are in position in the blocks, engage the opposite ends of the latter, as shown. The attafching members 6 are provided with bolt holes 7 and to said members are bolted the outer. ends-of tie rod attaching bars 8, said bars hav ng right angularly formed upwardly projecting outer ends 9 which are provided with apertures to receive the reduced threaded ends of rail tie rods 10. On the reduced portion of one end of the tie rods is screwed the clamping nut 11 whereby the shoulder formed by the reduced portion of reduced portion at the other end. On said longer end of the rod are arranged adjusting and clampingnuts 12 which engage the opposite sides of the right angularly bent end of the adjacent attaching bar whereby these parts and the rails may be adjusted laterally to maintain the rails at the proper age. a In addition to the attaching plates 4, the main supporting blocks 1 are provided with cushioning plates l of wood or other suit able material and with and engaging or supporting plates 13, the upper ends of which are bent at rightangles in one direction to provide plate engaging flanges 14 and at.

their lower ends are bent at right angles in opposite directions to form block engaging and supporting flanges 15 which hook under or are engaged beneath the opposite end of the block, is clearly shown in Fig. 8 of the drawings. Under certain conditions these plates 13 may be formed integral or connected together at their lower ends by forming the flanges 1-5 in one continuous strip beneath the plates, as shown in dotted lines in Fig. 8 of the drawings. The upper flanges 14: of the p'lates li-B- engage beneath the projecting attaching members U of the plates 4 and are provided with bolt holes through which and alined apertures in the attaching bars 8 and the holes 7 are inserted fastening bolts 16 on the upper ends of which are arranged rail clamping *wasliers 17 having beveled inner base flange engaging ends lb Which are engaged with the upper surface of the-base flanges ot' the rail and are clamped in operative position by means of nuts 19 which are screwed on the upper ends of the bolts 16, asshown'.

The rail tierods 10 are engaged With the attaching plates at the opposite ends of each alternate or mainsupporting block the iiitermediatc blocks 2 having no connection with each other. The supports are formed in separate blocks in the manner described,

and spaced apart to provide for the proper draina e of the surface water from between the rai s. In the channels 3 of the intermediate supporting blocks 2 are arranged wear plates 20, said plates having side flanges 21 to protect the base flanges of the rails and the adjacent walls of the channels 3 from wear. The ends of tl1Q 'Pl21tLt\S' 20' are ilso formed with extensions 22 which are adapted to be bentilownwardly at right ai'igles to engage the opposite ends of the blocks 2 as shown in Fig. 7 and to form stops to hold In addition to the plates, the rails are provided with cushioning devices in the form of blocks or slabs 4; formed of Wood or other suitable material which are engaged with said plates between their side flanges and are engaged by the rails when the latter are placed in position on the blocks.

In Figs. 10 and 11 is shown a modified fornioat supporting block 23, said block having formed therein a longitudinally disposed channel 25 and on the opposite ends of the block'are formed transverse recesses 26. In the lower part of the reeessedeiids ot the block are formed vertically disposed bolt receiving notches 27, with which are en-.

gaged rail fastening bolts 28. In therecessed ends 26 of the blocks and engaging the bolts 28 are tie rod attaching bars 33 which are similar in construction and operation to'the bars 8 described in the first figures of the'drawings. In the channels 25 of the block 24 are also arranged cushioning plates 30, the ends Of-'\\'lii(3l1 project. into the recessed portions of the ends cit-the blocks. The bolts 28 are provided with clamping clips 31 which rest on washers 31 to engage the base flanges of the rails and with fastening nuts 32 to secure the parts together. The blocks 23 are provided along their side edges with laterally projecting beads 3st which are adapted to support a clai'i'iping band 35 which is preferably arranged around the blocks to protect the notched ends of th same.

In Fig. 12 of the drawings, is showna dif ferent manner in which the threaded ends of the, tie rods may be secured to the rails to hold the latter in position. In this form, the rods 36 are constructed in the same manner as the rods 10 and the reduced threaded ends of the same are inserted through apertures 37 in the rails and havescrewed' or upsetting. When the rails are thus engaged by the tie rods, said rails are prefer-,

ably reinforced adjacent the connection of the rods with the rails by means of Washer or bracing plates 39 arranged on each side of the web of the rail where the aperture 37\ is formed. The plates 39 are also provided with apertures through which the threaded ends of the rods 36 are inserted and said,

plates are clampedfinto operative engagement with the opposite sides of therail Web by the nuts 3 From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form,- proportion and the minor details of coi'istrueti n ma be resorted to without departing from the principle or sacrificing any of the advantages of the invention, as defined in the appended claims.

I claim is:

1. In a railway rail support, a series of concrete blocks, cushioning and attaching plates arranged on -said blocks, attaching bars bolted to opposite ends of said attaching plates, means to clamp the base flanges of the rails into engagement with said attaching bars and plates, tie rods arranged between said attachin bars, and means whereby the ends of sai rods are adjust-ably secured to the bars.

2. In a railway rail support, a series of concrete supporting blocks, cushioning and attaching plates arranged on said blocks, end engaging and supporting plates arranged'mi the opposite ends of the blocks and in engagen'ient with tllQ'QlldS of said at- Having thus described my invention, what adjnstably connected to the inner ends of taching plate, attaching bars also engaged with the ends of said attaching plates, fastening bolts arranged through the engaging portions ofsaid attaching plates and bars, rail flange engaging washers on said bolts,'. fastening nuts adapted to be screwed into engagement with said washers to clamp the same against said rail flanges, and tie rods said attaching bars between the rails.

3. In a railway rail support, a series of 1 main and intermediate supporting blocks,'l rail engaging channels formed in said blocks, cushioning and wear plates arranged a in said channels, said wear plates having upwardly projecting side flanges arranged between the edges of the rail flanges and the ad acent walls of said channels, whereby said parts are prevented from wearing,
